Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: All voltage values are with respect to ground.

Note 3: When these pin voltages are taken below ground or above VDD,

they will be clamped by internal diodes. These products can handle input

currents greater than 100mA below ground or above VDD without latchup.

Note 4: VDD = 5V, fSMPL = 14kHz, internal reference unless otherwise

noted.

Note 5: Integral nonlinearity is deﬁned as the deviation of a code from a

straight line passing through the actual endpoints of the transfer curve.

The deviation is measured from the center of the quantization band.

Note 6: Bipolar zero error is the offset voltage measured from –0.5LSB

when the output code ﬂickers between 0000 0000 0000 and 1111 1111

1111. Unipolar zero error is the offset voltage measured from 0.5LSB

when the output code ﬂickers between 0000 0000 0000 and 0000 0000

0001.

Note 7: Full-scale bipolar error is the worst-case of –FS or FS untrimmed

deviation from ideal ﬁrst and last code transitions and includes the effect

of offset error. Unipolar full-scale error is the deviation of the last code

transition from ideal and includes the effect of offset error.

Note 8: Guaranteed by design, not subject to test.

Note 9: All speciﬁcations in dB are referred to a full-scale ±2.048V input

with a 2.5V reference voltage.

Note 10: Full linear bandwidth is deﬁned as the full-scale input frequency

at which the SINAD degrades to 60dB or 10 bits of accuracy.

Note 11: CB = capacitance of one bus line in pF (10pF ≤ CB ≤ 400pF)

Note 12: REFCOMP wakeup time is the time required for the REFCOMP pin

to settle within 0.5LSB at 12-bit resolution of its ﬁnal value after waking up

from sleep mode.

Note 13: High temperatures degrade operating lifetimes. Operating lifetime

is derated at temperatures greater than 105°C.
